Got a couple questions, I'll combine them instead of making two separate threads.

Pregunto numeró uno (hope that's right...lol): OK. Under settings->battery, there is a little graph that comes up and below the battery graph is a bar labeled "mobile network signal". I understand what it means, I just want to know what the colors are.

Question #2. Sometimes when I listen to music on my phone using Google Music, my phone will randomly quickly vibrate once, and then like 30 seconds later, quickly vibrate 3 times. Also sometimes it will actually randomly restart itself (isn't that called a "stop error"?).

I did do a search and couldn't find what I was looking for, so if there are threads about these topics, I apologize.
